Description

Technical Field

[0001] The utility model relates to the technical field related to windshield wipers, and in particular to a windshield wiper with a bent and formed fixed base. Background Art

[0002] Cars are generally equipped with wipers to scrape rain off the front windshield of the car. At the same time, oncoming rain needs to be diverted away when the car is driving, so the wiper will bear the friction of the glass, and that is to say, the connection between the wiper and the wiper arm will bear reciprocating tensile stress.

[0003] In order to ensure that the wiper arm will not be deformed or even broken, the existing wiper fixing base is made of die-cast or injection molding. In order to further improve the control of the wiper arm over the wiper and control the efficiency of the wiper in catching rain water, downwardly extending and bent fasteners are provided on both sides of the fixed base for wrapping the steel sheet. At the same time, an alignment hole is provided through the middle of the steel sheet, and a limiting column plugged into the alignment hole is also provided at the bottom of the wiper base.

[0004] Therefore, the wiper base occupies a large space and has many manufacturing processes, the overall production time is long, the efficiency is low, and the parts and materials are many and the cost is high; some wiper bases even need to be fastened with rivets. Utility Model Content

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When the number of an element is referred to as "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0027] like Figure 1-4 As shown, in the present embodiment, a wiper having a bent and formed fixed base 3 is provided, comprising a pair of steel sheets 2 provided with through holes 13, and also comprising a fixed base 3. In the present application, the fixed base 3 is actually a piece of hardware, which is bent to form the required three-dimensional structure. The fixed base 3 is provided with a downwardly extending alignment column 10. The fixed base 3 comprises a wall sheet 9 in the upper half, and the wall sheet 9 is formed by vertically bending upwards by protective sheets symmetrically arranged on both sides of the hardware sheet; an integrally formed splicing shaft 4 is also riveted between the two wall sheets 9, and the splicing shaft 4 is also formed by bending a pair of hardware sheets arranged at the top ends of the wall sheets 9, wherein one of the splicing shaft 4 hardware sheets is provided with a recessed groove and the other splicing shaft 4 hardware sheet is provided with a raised block. Therefore, when it is necessary to bend into the splicing shaft 4, the two five-pieces are bent so that the top is assembled and then further bent into a circular shaft structure.

[0028] Please refer to Figure 3In this embodiment, a pair of wall sheets 9 are respectively provided with a slide groove 8 in the middle part for buckling with the wiper arm. Because the vehicle is divided into left-hand drive and right-hand drive, the wiper direction is different for vehicles with different steering wheels. Therefore, the grooves 8 arranged between a pair of tensioning sheets 9 need to be asymmetrical with each other, so that it can be suitable for vehicles with different steering positions.

[0029] In this embodiment, the position of the alignment post 10 corresponds to the position of the through hole 13 on the steel sheet 2, and the alignment post 10 passes through the steel sheet 2 through the through hole 13; after passing through the steel sheet 2, the alignment post 10 is bent and fitted to the plane of the steel sheet 2 to rivet the steel sheet 2. In other words, the previous connection method of making the buckle 11 in addition to the alignment post 10 is abandoned, so as to achieve the purpose of aligning and tightening the steel sheet 2 at the same time.

[0030] In this embodiment, a pair of the steel sheets 2 are arranged at a distance from each other, a wiper strip 12 is clamped between the pair of steel sheets 2, an inwardly recessed sliding groove is provided on the top of the wiper strip 12, and the wiper strip 12 is clamped on the steel sheet 2 through the sliding groove. The purpose of setting the distance is to clamp the middle part of the wiper strip 12. The middle part of the wiper strip 12 is preferably not larger than the distance set between the steel sheets 2 to keep the wiper strip sliding.

[0031] In this embodiment, a pair of the steel sheets 2 are also sleeved on the top of a guide sleeve 5, which holds the edge of the steel sheet 2. At the same time, the guide sleeve 5 is provided with a guide strip extending to the top, which can effectively guide out some oncoming rainwater when in use. The guide sleeve 5 can further hold the two steel sheets 2 to avoid shaking. Fixed sleeves 6 are also respectively sleeved on both sides of the steel sheet 2; the fixed sleeves 6 are respectively fixedly connected to the two ends of the steel sheet 2, and the fixing method can be achieved by conventional means such as bonding. The fixed sleeve 6 can mainly limit the possibility of the guide sleeve 5 moving thereafter to achieve the reliability and stability of the overall wiper structure.

[0032] In another embodiment, in order to further stabilize the connection between the fixed base 3 and the steel sheet 2, a cover plate 1 is optionally sleeved on the fixed base 3, the cover plate 1 is provided with a through slot, the cover plate 1 is sleeved on the fixed base 3 through the through slot, and the cover plate 1 is provided with a fastening member 11 extending downward and buckled inward. The fastening member 11 extends to one side of the bottom of the steel sheet 2 to buckle the steel sheet 2, and the cover plate 1 is injection molded.

[0033] Please refer to Figure 2 In another embodiment, a stop column extending downward and abutting against the side wall of the steel sheet 2 is optionally provided on the edge of the bottom plane of the fixed base 3 to block the steel sheet 2 and prevent the steel sheet 2 from swinging.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
